Ametek / Elgar 320V Mod. Master Power Module

The Ametek/Elgar 320V Mod. Master Power Module is a modular power supply component designed for integration within the AT8000A/B programmable DC power supply system. It delivers ±320V DC output with current ratings of 0.625A at high voltage, derating linearly to 0.375A at 0V DC, and provides 200W maximum power. The module operates as a master unit in master/slave configurations, where up to five slave modules can be cascaded to increase available current and power per channel.

– Technical Specifications

• Voltage Output: −320V to +320V DC
• Current Output: 0.625A maximum (320V DC to 240V DC range); 0.375A maximum at 0V DC
• Power Rating: 200W
• Operating Modes: Constant Voltage, Constant Current
• Protection: Overcurrent sensing; overvoltage protection with SCR crowbar shutdown
• Output Relay: Integrated load isolation relay

– Key Features

• Master module identification via discrete integrated circuits on DAC board (distinguishing feature from slave modules)
• Ribbon cable interconnects for programming distribution to slave modules—no power transmission through control cables
• Channel assignment determined by master module slot location within chassis
• Master/slave combinations support two to six modules per channel

– System Integration

The module integrates into Elgar AT8000A/B systems supporting up to 16 independent channels across multiple chassis, with aggregate power capability reaching 19.2 kW. Up to six modules (power supply or electronic load variants) occupy a single 5.25-inch mainframe. Local control operates via front-panel keyboard; remote operation uses GPIB (IEEE-488) interface. The system qualifies for ATE environments with MATE and CIIL programmability support.

– Compatibility & Integration

Designed exclusively for AT8000A/B platform deployment. Requires one master module per channel. Supports cascaded slave module configurations for distributed load current across multiple units.
